Instead of filling in the struct v4l2_capability device_caps
field, fill in the struct video_device device_caps field.
That way the V4L2 core knows what the capabilities of the
video device are.

Hi Andrey,
I noticed this new staging V4L2 driver. FYI, please CC any future patches to
this driver to the linux-media@xxxxxxxxxxxxxxx mailinglist as well so we can
review it. I'll post a review of this driver later today as well. In the
meantime, I'd like to get this patch in since during the upcoming 5.4 cycle
we will require that the device_caps field of struct video_device is set
correctly.
Greg, do you want to take this patch? After Andrey Acks it, of course.
Regards,
Hans
